Chapter 3 CIP Safety I/O for the GuardLogix Control System Diagnostics CIP Safety I/O modules perform self-diagnostics when the power is turned ON and periodically during operation. If a diagnostic failure is detected, safety input data (to the controller) and local safety outputs are set to their safe state (OFF). Status Data In addition to safety input and output data, CIP Safety I/O modules support status data to monitor module and I/O circuit health. Refer to your module’s product documentation for specific product capabilities. Status Indicators The CIP Safety I/O modules include status indicators. For details on status indicator operation, refer to the product documentation for your specific module. On- or Off-delay Function Some CIP Safety I/O modules may support On-delay and Off-delay functions for input signals. Depending upon your application, you may need to include Off-delay, On-delay, or both when calculating system reaction time. See Appendix C for information on system reaction time. 30 Publication 1756-RM093F-EN-P - January 2010
CIP Safety I/O for the GuardLogix Control System Chapter 3 Reaction Time The input reaction time is the time from when the signal changes on an input terminal to when safety data is sent to the GuardLogix controller. The output reaction time is the time from when safety data is received from the GuardLogix controller to when the output terminal changes state. For information on determining the input and output reaction times, refer to the product documentation for your specific CIP Safety I/O module. See Appendix C for information on calculating the system reaction time. Safety Considerations for CIP Safety I/O Modules You must commission all devices with a node or IP address and communication rate, if necessary, before their installation on a safety network. Ownership Each CIP Safety I/O module in a GuardLogix system is owned by one GuardLogix controller. Multiple GuardLogix controllers and multiple CIP Safety I/O modules can be used without restrictions in chassis or on networks as needed. When a controller owns an I/O module, it stores the module’s configuration data, as defined by the user. This controls how the modules operate in the system. From a control standpoint, safety output modules can only be controlled by one controller. Each safety input module is also owned by a single controller; however safety input data can be shared (consumed) by multiple GuardLogix controllers. Safety I/O Configuration Signature The configuration signature defines the module’s configuration. It can be read and monitored. The configuration signature is used to uniquely identify a module’s configuration. When using a GuardLogix controller, you do not have to monitor this signature. It is monitored automatically by the GuardLogix controller. Publication 1756-RM093F-EN-P - January 2010 31
